Fig. 19From: Ocular ultrasonography focused on the posterior eye segment: what radiologists should knowProliferative diabetic retinopathy (PDR). a Fundoscopy image shows extensive neovascularization (arrows), the hallmark of PDR. b US images in a 72-year-old diabetic man with PDR and a history of recurrent vitreous haemorrhage. Note the vitreous bands due to chronic vitreous haemorrhage (arrows) and preretinal fibrovascular membranes (arrowhead). c At the 3-month follow-up, the fibrovascular tissue has grown into the vitreous cavity (arrowhead), and the patient has developed posterior vitreous detachment (arrow), retrohyaloid haemorrhage (asterisk), and focal retinal detachment (curved arrow). He subsequently underwent vitrectomy and panretinal laser photocoagulationBack to article page
